In recent years, most illegal drugs have entered the US through (D) Mexico; in the 1980s, most came from Colombia.
In the last few years, smugglers have managed to sneak drugs across the border in different ways. Most of them have hidden drugs such as cocaine and heroin in their vehicles or in their shoes. In addition, in the last two decades more than 200 tunnels used to transport marijuana and cocaine have been discovered on the Southwest border. However, in the 1980s, most drugs entered the US from Colombia due to the Medellin Cartel led by Pablo Escobar. This drug cartel processed coca imported from Bolivia and Peru into cocaine and then distributed it through different trafficking routes in the United States, including Florida, California and New York.
